Although the post was in October, Sam would have been working on her clothing range then, as she told Forever Sewing that she was launching her brand in August.

In the picture, Sunday is wearing a cute light brown jumper and matching pants, with a furry gilet on top and a headband.

The official Forever Sewing Instagram account is tagged in the picture.

Laura Newman, who owns Forever Sewing with her husband, had shared screenshots of messages sent between her and Sam going back over two years.

They show Sam asking for dozens of items of free clothing for her pre-schooler son Paul Knightley, and promising to give the family-run business plenty of exposure on her ITV reality show Mummy Diaries.

But Laura said she was "devastated" when Sam and her partner Paul Snr announced they were launching their own bespoke kids clothing range, My Little Darlin - which boasted designs very similar to those of Forever Sewing.
